Specification of Letters Patent.

Patented April 23, 1907.

Application filed May 15, 1906- Serial No. 260,499.

To all whom it may concern: v

Be it known that-I, MrnroN F. WILLIAMS, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Crushers, of which the following is a full, clear; and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the. accompanying drawings, forming part of this specification, in which- Figure 1 is a view in elevation of the hammers and hammer supports of a crusher and pulverizer constructed in accordance with my invention; Fig. 2 is an enlarged fragmentary elevation of the same; and Fig. 3 is an end view of the hammers.

This invention relates to the class of crushers and pulverizers, and one of the objects of the invention is to improve the construction of the disintegrating mechanism and particularly the hammers and their connecting supports.

Another object of the invention is to provide meanswhereby the hammers or beaters will besupported around an axis in staggered relation to each other and in such a manner that the In'aterialmay be thoroughly acted struction may be resorted to without departing from the spirit of my invention or sacrificing any of the advantages thereof.

The preferred embodiment of my invention as illustrated in the accompanying drawings includes a shaft 1 carrying a plurali.y of alternately arranged hammer supports comprising arms 2 and 3 which are keyed to the shaft. These arms have central openings through which the shaft projects, said arms being approximately rectan lar in form, and each alternate arm is at right angles to the adjacent one.

each other but alternate with thoseon the adjacent arm. In other Words, the hammers on the respective arms align with the adjacent arm and are of about the same thickness as said arms. It will be observed that by this arrangement the weight of the hammers 6 will be evenly distributed around the axis of the shaft 1, and all of the material will be evenly acted upon, which material may be placed Within a casing 7 having a cage or grate 8-in the bottom thereof.

Having thus described my invention, what I claim asnew and desire to secure by Letters Patent is:

In a device of the character described, the

combination of hammer supports comprising oppositely disposed connected arms secure to said shaft, an auxiliary air of hammer supports comprising opposite y disposed connected arms also secured to saidshaft and extending at substantially right angles to the first mentioned arms, and hammers on each of said arms, the hammers on the arms of one-pair being arranged upon the same side and the hammers on the arm of the auxiliary pair being arranged upon the same side but the side op osite to that on which the first mentioned arms are mounted, whereby the hammers are in the same plane with the arms of the adj[acent pair.'

In testimony whereof, hereunto affix. my signature, in the presence of two witnesses, this 11th day of May 1905. r

MILTON F. WILLIAMS.
